Ecologically Sustainable Development (ESD)

The management of an activity to achieve an on-going minimization of the activity's environmental harm through cost effective measures assessed against the measures currently used nationally and internationally for the activity. Source: A3

Economic Life

The period from the acquisition of the asset to the time when the asset, while physically able to provide a service, ceases to be the lowest cost alternative to satisfy a particular need.

The economic life is at the maximum equal to the physical life but obsolescence will often ensure that the economic life is less than the physical life. Source: G1

Effective Life

The effective life is the period during which an asset can be used for income producing purposes. The Period is calculated based on the asset's expected use and the assumption that it is maintained in reasonably good order and condition.

Over time the estimated effective life of an asset may become inaccurate and changed if:

use of the plant is greater or less vigorous than originally estimated

Efficiency

A measure of resource commitment to the activity per unit of output from the activity. After the fact, this can be assessed by comparing resource input against actual output. Source: N1

Environmental Impact Appraisal

An environmental review supporting a negative declaration, i.e., the action is not a major Federal, State, or private sector action significantly affecting the environment. It describes a proposed EPA action, its expected environmental impact, and the basis for the conclusion that no significant impact is anticipated. Source: A4

Environmental Impact Statement

A document required by Federal and/or State legislation for major projects or proposals. It provides information for decision makers on the positive and negative effects of the undertaking, and lists alternatives to the proposed action, including taking no action.

For example, an environmental impact assessment report, prepared by an applicant's experts for a Development Application, identifies and evaluates the environmental impacts of the applicant's proposed development and investigates all feasible alternatives. Source: S1

Environmental Management

The use of procedures that minimize adverse environmental impact during construction and site operation. Source: S2

Equipment

Apparatus, appliances, devices, fittings, fixture, furniture, materials and the like, used as part of, or in connection with an asset, but that are not permanently attached to, or are removable from, that asset. (An item of major equipment may be an asset in its own right.) Source: D1
